Application method of special anti-counterfeiting material in packing box

Abstract

The invention provides an application method of a special anti-counterfeiting material in a packing box. The method comprises the steps of: heating anodized aluminum through a hot printing plate, melting a stripping layer, and melting an adhesive layer; bonding the adhesive layer to a printed material during printing, separating a coloring layer from a polyster film base layer, and remaining an aluminum coating and the coloring layer on the printed material; printing after heating: hot printing holographic laser anodized aluminum on a special-color ink, and printing UV (Ultraviolet) ink on the anodized aluminum; and carrying out the processes of embossing, film laminating, reprinting, box pasting, and the like after hot printing. The application method is characterized in that the anodized aluminum with a surface tension of (4.0-4.6)*10-2N / m is selected to ensure good adhesive force of the ink, and the surface tension of the UV ink is above 3.8*10-2N / m. In the invention, a three-dimensional pattern is realized by using the anodized aluminum through a holographic laser anti-counterfeiting technology, the integration of a printing bottom with the three-dimensional pattern and effective anticounterfeiting are achieved, and the appearance of the packing box is attractive. The method is favorable for reducing material consumption and cost, and can realize three-dimensional hot foil printing on various paper materials.

Description

technical field [0001] The invention relates to an application method of a special anti-counterfeit material on a packaging box, in particular to an application method of a special three-dimensional material on a packaging box. Background technique [0002] The known three-dimensional anti-counterfeiting printing generally means that the surface of the printed product of the packaging box is covered with a layer of concave-convex lenticular lens-shaped lenticular sheet. The concave-convex lenticular lens-shaped grating sheet is made of polystyrene raw material through injection molding. Polystyrene is colorless and transparent (88%-92% transparency), with a refractive index of 1.59-1.6, non-extensible and flammable. It has a good luster due to such a high refractive index. The processing of transparent plastics produces birefringent stress, that is, optical effects. When people observe an object, due to reasons such as the angle of view between the two eyes, the image of ...

Secondly, the choice of adhesive for bonding the printing bottom surface to the lenticular film is particularly important, not only to make the printed matter and the lenticular film stick together firmly, but also to protect the ink layer from discoloration under high temperature, so that the operation and materials are more convenient. The choice brings difficulty

Again, if the grating sheet is torn off, it cannot be anti-counterfeiting
